Title: Silicon nanoparticle electronic switches
Inventor: SMITH ADAM D
IPC: H03K17/51
Filed: 2002-02-08
Granted: 2007-12-18
Abstract: An electronic fast switch for operation at room temperature utilizing uniform silicon nanoparticles (.sim.1 nm with about 1 part per thousand exceeding 1 nm) between two conducting electrodes (10,18). The silicon nanoparticles, when on an n-type silicon substrate exhibit, at zero bias, a large differential conductance, approaching near full transparency. The conductance is observed after one of the electrode is first biased at a voltage in the range 3 to 5 eV  (switching voltage), otherwise the device does not conduct (closed). A  practical MOSFET switch of the invention includes the silicon nanoparticles (16) in a body of the MOSFET, with the gate (24) and substrate (22) forming the two conducting electrodes. Electrodes may be realized by metal in other switches of the invention.

Abstract: A flow meter incorporating thermal loss sensors and an installation adapter to provide known flow conditions upstream of the meter. The installation adapter is in the form of a tubular extension projecting from a flange which in use is sandwiched between a pipeline flange and a flow meter flange. The flanges are configured such that a passageway defined by the adapter extension is located in a predetermined position relative to the flow meter. The flow meter may comprise a sensor array supporting at least three sensors which are not in alignment, one of those sensors being located centrally within the flow meter and the others being distributed at equal distances around the central position. In use, normal readings may be taken from a single one of the sensors, the other sensors being used for initial calibration and subsequent calibration test purposes only. A comparison is made between the relative values of the outputs of the different sensors to identify sensor drift or potentially significant changes in flow conditions.

Title: Method for fabricating chirped fiber bragg gratings
Inventor: UNRUH JAMES OWEN
IPC: G03F1/34
Filed: 2002-08-22
Granted: 2010-02-16
Abstract: A chirped Bragg grating is fabricated in an optical fiber by exposing the fiber to a coherent beam of light through a parallel phase mask having a series of progressively chirped segments produced on a lithography tool. The chirped phase mask is fabricated by exposing a photoresist-coated substrate to an image writing element such as an electron beam or a laser according to a set of parameters provided to the lithography tool. The parameters include a basic grating pattern for each segment, a value that defines the expansion or contraction of the grating pattern and an axis location to which the grating pattern is to be written to the substrate. By selecting machine commands that implement these parameters with a minimum throughput overhead, the mask can be produced in a reduced time, and therefore with increased accuracy .

Abstract: A present invention provides an internal circulating irradiation capsule available for the production of iodine- 125 and a related production method. The irradiation capsule filled with xenon gas has a lower irradiation part, an upper irradiation part, and a neutron control member. The lower irradiation part is inserted into an irradiation hole of a reactor core and irradiated with a large quantity of neutrons directly. When neutrons are radiated to the xenon gas, iodine-125 is produced from xenon gas. The upper irradiation part protrudes from the irradiation hole, and iodine-125 is transferred to the upper irradiation part by convection and solidified in the upper part. The neutron control member reduces neutrons in the upper part to produce iodine-125 of high purity and radioactivity in a large quantity.
